一种新的多重代理多重数字签名方案

New multi-proxy multi-signature scheme

基于离散对数问题,提出了一种新的多重代理多重签名方案,该方案指定了签名验证人,在门方案的基础上又完善了签名过程,最终签名由其中一位代理人给出,从而避免了门方案中不具有追踪性、可滥用签名权的漏洞,签名体现了签名者身份信息,进一步防止了伪造攻击,是一种相对安全的多种代理多重数字签名方案。

Based on discrete logarithmic,this paper proposed a new multi-proxy multi-signature scheme. This scheme called on the verifier of the signature and perfected the progress of signature based on the Men scheme. The last signature was given by one of the proxy,so that avoid the shortage of untraceble and abuse signature right in the Men scheme. The signature included the information of signers’identification,and could keep off the forgery attack. So it was a multi-proxy multi-signature scheme which was comparatively safe.
